WINDOW.

SPECIFICATION forming part of Letters Patent No. 617,186, dated January3, 1899.

Application filed February 19, 1898. Serial No. 670,986. (No model.)

To all whom it may concern-.-

Be it known that I, MARTIN RILEY, a resident of Washington, in theDistrict of Columbia, have invented certain new and useful Improvementsin Vindows; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it pertains to make and use the same.

This invention relates to windows and window-frames; and it has for itsobject to provide a simple, durable, and comparatively inexpensivewindow-frame adapted to be easily removed from its casing when desiredand to provide means for counterbalancing the sash independent of theuse of weights; and it consists of the parts and combinations of partshereinafter described and claimed.

In the accompanying drawings, forming a part of this specification,Figure 1 is an in side front elevation of the window with my inventionin place; Fig. 2, a similar elevation from the outside; Fig. 3, a bottomend view of the window-frame removed from the casing; Fig. i, across-section on the line 4 4:, Fig. 1; Fig. 5, a vertical longitudinalsection through the window-casing; Fig. 6, is a vertical section throughthe upper half of the window-frame; Fig. 7, a detail view, partly insection, of the escapement tube and valve; Fig. 8 a, detail frontelevation of the sashlocking device; Fig. 9, a detail side elevation ofthe sash-locking device; Fig. 10, a detail perspective of the lever foroperating the lock-bolt; Fig. 11, a detail perspective of the hinge forhanging the window-frame in the casing, and Fig. 12 a perspective viewof a tool for removing the caps from the cylinders.

Similar letters refer to similar parts throughout all the views.

Referring to the drawings, A represents the wind0w-casing,which may beof ordinary construction and is provided with the projecting crossplates or strips a at about the center of the top and bottom bars,whichare adapted to enter grooves b in the sashes B to prevent the entranceof dust. IVithin the casing A is hung the window-frame O, which consistsof the side bars c,having a longitudin al groove cl therein at the outerside and a similar groove e at the inner side, the said bars obeingconnected by a front cross-bar f at their bottom ends. To the upper endof the frame 0 are secured the hook-plates g of the hinge, thebar-plates h of said hinges being secured to the top bar of thewindow-casing A, whereby the frame 0 may swing out on said hinges or isunhooked and bodily removed from the casing.

In the inner grooves e of the frame 0 are secured the parallel metalbars 2', which extend from the bottom to top of said grooves and whichfit within grooves 3' formed in the sash B, so as to serve as a guidetherefor. In the outer groove cl is arranged the locking device for thesash, which consists of a fiat spring 1E, having one end secured to theframe 0 and the other or free end provided or formed with a bolt is,which extends through an opening]. in the frame 0 in position to engagea notch or notches m formed in the edges of the sash in order to lockthe sash in any position to which it may be adjusted. The spring E ismoved so as to disengage it from the sash by means of a bent lever F,Fig. 10, having a right-angled projection nat one end which engages saidspring, said lever being pivoted to the frame C and connected bya wire0, passing through a screw-eye in the frame to a pushbutton 19,-wherebyupon pulling said button outwardly said lever will operate to draw thefree end of the spring away from the sash and thus release the same, andupon releasing the button the spring will fly back, carrying the boltinto position to engage the notch.

The sash-frames B are provided at each side with a cylinder H, intowhich a rod I, having an enlarged head forming a piston, extends. Thecylinders are provided at each end with screw-caps P, having a nick orgroove in their heads, into which a screw-driver may be inserted inorder to remove the same, the upper cap being easily removed by anordinary screw-driver; but the lower cap, owing to the fact that thepiston-rod extends therethrough, requires a peculiarly-constructedtool,such as shown in Fig. 12, consisting of a bar or handle having aflat, bent, and slotted end adapted to receive the piston-rod in theslot and to engage the notch in the cap to remove it. At

their upper ends the cylinders H are connected in each sash by a tube L,extending through the top rail of the sash, in which tube an opening isformed to receive the plug or valve 4', carried on the end of a spring8, secured in the upper bar of the sash. This spring is depressed so asto withdraw the plug or valve from the opening by means of a lever M,fulcrumed to the sash and having one end engaging the spring, the otherend of said lever being connected to the end of a cord N, which passestherefrom through a screw-eye in the sash, so that upon pulling saidcord the free end of the lever will draw the spring down and the plugout of the opening in the tube, thus permitting the air to escape andthe sash to be lowered. The cord is only necessary in connection withthe top sash, as the lever on the lower sash may be easily reached andoperated by the hand. The piston-rods I are held rigidly by means of theplates P, pivotally secured to the ends of the frame C,-said platesbeing notched to engage grooves formed in the lower ends of the rods tohold them in position. The frame O is held in place in the window-casingby a hasp-hinge '15, secured to the sill of the casing and having aslotted leaf, through which a screw-eye secured to said frame 0 passesand which may be turned to fasten the parts together.

When it is desired to screen the window, it is easily accomplished byhinging a screen to the top of the casing outside, as shown in Figs. 2and 5, the screen B being provided with bars u, (shown in dotted lines,Fig. 5,) which are pivoted to the casing and to the screen and alsotogether at their meeting ends, said ends being slightly bent so as tointerlock when fully extended in order to sustain the frame in aninclined position, as shown in Fig. 5; also, said screen may serve thepurpose of an awning when in the position shown in Fig. 5 by arranging acurtain V, having a spring-roller of any desired or preferred styleattached to the top crosspiece of the screen-frame and having cordsrunning therefrom to and through screw-eyes o, secured to the bottomcross-pieces of the screen-frame. (See Fig. 5.)

through the tube L. hen the sash is raised the desired height, the leveris released, closing the valve, and thus confining the air in thecylinders, the pistons acting as a cushion or support for the sash tohold them in the position to which they are raised. To lower the sash,it is only necessary to open the valve and permit the air to escape fromthe cylinder through the tube L.

The sash may be locked in place by the locking device described, andsaid device also acts in case of emergency to support the sash whenraised.

Having thus described my invention, what I claim as new, and desire tosecure byLetters Patent, is v 1. The combination, with a window-frame,of sash having air-cylinders at each side thereof, pistons for saidcylinders having their rods secured to the window-frame and a suitablevalve for said cylinders.

2. The combination, with a window-frame, of sash having air-cylinders ateach side thereof, a tube communicating with said cylinders, a valve forsaid tube to control the admission and exit of air, and suitable pistonsfor said cylinders.

3. The combination with a window-frame, of sash having air-cylinders ateach side, a tube connecting said cylinders, a valve for said tube,pistons for said cylinders, and a locking device for said sash.

4. A WlIIdOW, comprising a permanent casing, a swinging and detachablewindow-frame, sash for said frame having air-cylinders at each side,pistons for said cylinders having their rods secured to said frame, atube provided with a valve connecting said cylinders, a locking devicefor said sash, and means for securing the frame in the casing.

I claim in my invention many new and original improvements, and intestimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

MARTIN RILEY.
